Problems solved by technology

The steel strand pulling device currently used on the market mainly relies on the friction force of two cylindrical rollers to pull the steel strand. This device has no restriction on the lateral movement of the steel strand. The steel strand deviates, resulting in slight bending of the steel strand, which affects safe use
Moreover, most of the traction devices on the market are single or two steel strands, which cannot adapt to larger-scale production.

Abstract

The invention discloses a drawing device for prestress steel strands. The drawing device is characterized in that a driving drawing shaft, a plurality of driven intermediate wheel shafts and a plurality of driven drawing shafts are hinged in a box; one end of the driving drawing shaft is connected with a motor reducer, and driving gears are arranged at the other end of the driving drawing shaft, the ends of the driven intermediate wheel shafts and the ends of the driven drawing shafts and are meshed with one other; a plurality of driving drawing gears are arranged on the driving drawing shaft and the driven drawing shafts; a plurality of driven drawing gears are mounted on a plurality of pressing shafts hinged to movable bearing seats, the movable bearing seats are slidably used in slide grooves in the box, and movable driving mechanisms are connected to the movable bearing seats and drive the same to move. The drawing device has the advantages that the steel strands are pulled by the driving drawing gears and the driven drawing gears to run simultaneously, efficiency is high, structure is simple, and cost is low.

Description

technical field [0001] The reinforcing bar traction device of the present invention particularly relates to a prestressed steel strand traction device. Background technique [0002] The steel strands are generally packaged in bundles, how to effectively pull them in actual use not only relates to the smooth implementation of the follow-up process, but also affects the smooth unwinding of the steel strands. The steel strand pulling device currently used on the market mainly relies on the friction force of two cylindrical rollers to pull the steel strand. This device has no restriction on the lateral movement of the steel strand. The steel strand deviates, resulting in slight bending of the steel strand, which affects safe use. And most of them are single or two steel strand pulling devices on the market now, which cannot adapt to larger-scale production. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, an...
